Every few thousand years, the Sun unleashes a burst of high-energy particles that can have serious consequences for life on Earth.
NASA's Global-scale Observations of the Limb and Disk (GOLD) mission has revealed unexpected C- and X-shaped formations in an electrified layer of gas high above our heads called the ionosphere.
Our planet was born around 4.5 billion years ago. To understand this mind-bendingly long history, we need to study rocks and the minerals they are made of. In a new study, evidence of rocks of a similar age were found in Australia.
The hunt for the origin of garnet crystals found on South Australian beaches took researchers thousands of kilometres and half a billion years back in time to a hidden Antarctic mountain range.
Deep beneath our feet, in the heart of our planet, something unexpected is happening. Scientists have discovered that Earth’s inner core, a solid iron-nickel sphere roughly the size of the moon, is slowing down.
Geoscientists show that rocks from the Isua Supracrustal Belt in West Greenland have experienced three thermal events throughout their geological history.
New research finds Earth's surface was first sprinkled with fresh water some 4 billion years ago, a whole 500 million years earlier than previously thought.
Because it was an underwater volcano, Hunga Tonga produced little smoke, but a lot of water vapor: 100–150 million tonnes, or the equivalent of 60,000 Olympic swimming pools.
A solar storm that filled Earth's skies with shimmering curtains of light in May 2024 was so intense that its effects were felt, even at the bottom of the ocean.
The same geomagnetic storms causing the auroras can cause havoc with our planet’s human-made infrastructure.
On the scale of cataclysmic events, the whomping impact of a Mars-sized object that crashed into Earth some 4.5 billion years ago ranks pretty highly: thought to have set in motion the movement of our planet's fractured, rocky crust.
The recent discovery of a Roman dodecahedron in Lincolnshire has prompted renewed fascination in these ancient mysterious objects.
Earth's magnetic field nearly collapsed some 590 million years ago, presumably putting life on the planet's surface at risk of a rise in cosmic radiation.
Rocks that formed some 3.7 billion years ago in the early Archean have given us the earliest glimpse yet of Earth's magnetic field.
The 390-million-year-old forest landscape, archived within the Eifelian Hangman Sandstone Formation of Somerset and Devon in England, is roughly 4 million years older than the previous record holder.
